LANDING-CARRIAGE F033, FLYING-MACHINES.

naaaesa Specification of Letters Patent.

Application filed April 22, 1919. Serial No. 292,002.

To all whom it may concern:

shocks likely to be transmitted to the fuse lage on the landing ofthe machine and in addition consists in the arranging of the parts of the carriage so as to efi'ect a proper balancing thereof.

tVith this end in view the carriage comprises an arrangement of stayrods separately associated with the axle and elastically and universally connected with the fuselage.

The annexed drawing represents by way of example two forms of the construction of the invention.

Figures '1, 2 are respectively a side view and a front view of a landing carriage.

Figs. 3, a are respectively aside view and a front view of the second form of landing carriage. I

The landing carriage comprises an axle 1- bearing the wheels --2; the stays -3--3-- pivoted at their lower ends --9- through ball and socket joints -l0- to turnable rings -5 mounted on the end of axle 1--, said stays being inclined one toward the other as well as with respect to a vertical plane passing through the axis 'one'another, by means of a transverse bar --16 which passes thrbugh slots 15 in said stays' The upper head of said stays are provided with stirrups. 14- over which pass the caoutchouc cables -'13-, wound on bar -16-. The rods --17- are pivoted at their ends respectively on central bracket l8 of bar 16 and on the head portions of stays --3-3'--..

The rear stays '4c are connected at" their lower ends to the rotatable rings -5-- while their upper ends are connected to the fuselage frame through ball and socket oints 12- the sockets being fastened on brackets -11- depending from said frame.

A ball and socket connection ."12 is provided between the upper ends of rear stays tand the longitudinals --8, the

"sockets being fastened on a bracket --11--..

lnthe form of construction represented in Figs. 3-dthe upper ends of stay rods --3-3--' are vpivotally connected to the ends of a laminated spring -19-- by means of ball and sockets -66 said spring being fastened by stirrups --Zl-, to the central longitudinal -8-- of the flying machine.

The stay rods --d--d'- have a common socket and ball connection --11 12 with Patented ma a, rose.

the under portion of the aeroplane frame. 7

Having nowrparticularly described my invention and the manner in which the same should be performed 1 claim 1. Tn a flying machine having a fuselage frame, a landing carriage comprising a wheel axle, rotatable rings at the ends of said wheel axle, two rear stay rods connected at their lower ends to said rings and inclined to one another as well as in respect of a vertical plane passing through said fuselage frame, two fore stay-rods joined at their lower ends by ball and socket conmotions to said rings, said rods being inclined to one another as well as in respect to a vertical plane passing through the axle,

elastic universal connections between the upper ends lot the latter mentioned rods and the fuselage frame. g

2. In a flying machine having a fuselage frame, a landing carriage comprising a wheel axle, rotatable rings at the ends of said wheel axle,- two rear stay, rods connected at their lower ends to said rings and inclined to one another as well as in respect of a vertical plane passing through said axle, ball and socket connections between the upper ends of said rods and the fusetoo lage frame, .two fore stay rods joined at their ends by" ball and socket connections to said rings, said rods being iriclinedito the end sections of said fore stayrods and one another as well as in respect to a vertical ball and socket connections interposed in plane passing through the axle, the end said last mentioned rods.

sections ofthe rods beingprovided with In testimony whereof I affix my signa-- .5 longitudinal slots, stirrups on the heads of tnre in the presence of two witnesses.

said sections; a transverse bar depending GIANNI C from the fuselage frame, elastic bands L wound on'said bar. and passing over said Witnesses:

stirrups, other rods arranged respectively G. G. GUANINI,

10 between a point of said transverse bar and E. O. BURKE.
